Notes:
Crystallization of a series of ZnO-P2O5 based glasses was investigated. ZnO-P2O5-CaO glasses could be converted most readily to glass-ceramics and crystallization of these led to formation of alpha-Zn2P2O7, alpha-CaZn2(PO4)2, and ß-CaZn2(PO4)2 phases. A further phase has been tentatively identified as monoclinic (Zn,Ca)2P2O7. The most promising glass-ceramic composition Z15 (59.4ZnO·33P2O5·6.6CaO·1SiO2) crystallized to alpha-Zn2P2O7 and ß-CaZn2(PO4)2, the latter phase being stabilized by the presence of SiO2 which also encouraged volume nucleation giving a fine-scale (submicrometer) microstructure.
